Serial No. 763.376.

To (ZZZ 7.0720222. it may COHC'CMZ Be it known that I, RUDoLr V. MANN, acitizen of the United States, residing at Claflin, in the county ofBarton, State of Kansas, have invented certain new and usefulImprovements in Devices for Applying Leather Facings to Pulleys; and l Ido hereby declare the following to be a 1 full, clear, and exactdescription of the in- I vention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to devices for plying leather facings to pulleys.

The object of the invention resides in the provision of a device of thecharacternamed which will enable leather facings to be applied to theperipheries of pulleys with ease and facility and in an efficientmanner.

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which- Figure 1 is aside elevation of a pulley showing a strip of leather held around theperiphery of the pulley, the one end of the strip being unattached tothe periphery; Fig. 2, a partial side elevation showing the strip cut tolength and both ends thereof secured to the periphery of the pulley;Fig. 3, a plan view of what is shown in Fig. 1; Fig. 4c, a section onthe line M of Fig. 3; ig. 5, a section on the line 55 of Fig. 1, and Fig. 6, a section on the line 66 of Fig. 2.

Referring to the drawings A indicates a pulley which includes the usualspokes 10 and rim 11 around which latter a leather facing is adapted tobe applied through the instrumentality of the improved device.

The device is shown as comprising a pair of parallel spacedcorresponding L shaped members B each of which includes a long arm 12and a short arm 13. Each of the long arms 12 is provided with a seriesof openings 14-, while the short arms 13 are provided respectively withopenings 15. The outer ends of the short arms 13 are providedrespectively with outwardly directed extensions 16 and these extensionsare pro- Hlrsorrvided with bolt openings 17. Disposed i against theextensions 16 is a bar 18 pro vidcd at each end with openings 19 adaptedto register with the openings 17 and engaged through the registeringopenings 17 and 19 are bolts 20. In this manner the L- shaped membersare connected together in parallel spaced relation as will be obvious.The number of openings 19 is in excess of the number of openings 17which will permit the L-shaped members B being connected to the bar 18at different distances apart so that said L-shapcd members can beapplied in embracing relation to pulleys of different widths. The bar 18is provided with a central opening 21 in which is slidably engaged a rod22 one end of which is threaded as at 23 and the other end thereof bentlaterally and engaged through an opening 2st formed centrally in a plate25. The plate 25 is provided on each side of the opening 24 withopenings 26 through which are engaged bolts 27. Engaged on the threadedend 23 of the rod 22 is a nut 28 which is adapted to bear against theface of the bar 18 remote from the plate 25 during the operation of thedevice. Engaged through corresponding openings 15 of the short arms 13is a rod 29 which is adapted to bear against one of the spokes 10 duringthe use of the device as will hereinafter appear. Detachably engaged incorresponding openings 14 of the long arms 12 is a rod 30 upon which isjournaled between the arms 12 rollers 31. It will be apparent that therod 30 can be adjusted toward and away from the outer ends of the arms12 so as to position the rollers 31 to accommodate pulleys of differentdiameters.

In the use of the device one end of a strip of leather indicated at C,is made fast to the rim 11 by the usual rivets. The strip is then passedaround the periphery and secured by the bolts 27 to the plate at a pointin said strip that will overlap the fixed end of the strip. The membersB are then disposed in embracing relation to the pulley and the rods 29and 30 applied in the proper manner, the position of the rod 30 beingsuch as to dispose the rollers 31 relatively near the strip C. The nut28 is then manipulated inwardly of the rod 22 which will force the rod29 in engagement with a respective spoke 10.. and stretch the strip Gupon the rim 11. When the strip 0 has been sufficiently stretched theloose end end of said rod, a nut threaded on the other thereof issecured to the rim by the usual end of the rod, means for securingfacing rivets and the strip cut so that the ends material to said plate,a rod detachably enthereof will be disposed in abutting relation. gagedthrough the openings in the arms of The applylng of the facing to thepulley is the L-shaped members secured to the bar,
